Application Precautions
Observe the following precautions when using the PLC System.
!WARNING
Always heed these precautions. Failure to abide by the following precautions
could lead to serious or possibly fatal injury.
• Always connect to 100
Ω
or less when installing the Units. Not connecting
to a ground of 100
Ω
or less may result in electric shock.
• Always turn OFF the power supply to the PLC before attempting any of
the following. Not turning OFF the power supply may result in malfunction
or electric shock.
• Mounting or dismounting Expansion Units or any other Units
• Connecting or removing the Memory Cassette or Option Board
• Setting DIP switches or rotary switches
• Connecting or wiring the cables
• Connecting or disconnecting the connectors
!Caution
Failure to abide by the following precautions could lead to faulty operation of
the PLC or the system, or could damage the PLC or PLC Units. Always heed
these precautions.
• Install external breakers and take other safety measures against short-cir-
cuiting in external wiring. Insufficient safety measures against short-cir-
cuiting may result in burning.
• Mount the Unit only after checking the connectors and terminal blocks
completely.
• Be sure that all the terminal screws and cable connector screws are tight-
ened to the torque specified in the relevant manuals. Incorrect tightening
torque may result in malfunction.
• Wire all connections correctly according to instructions in this manual.
• Always use the power supply voltage specified in the operation manuals.
An incorrect voltage may result in malfunction or burning.
• Take appropriate measures to ensure that the specified power with the
rated voltage and frequency is supplied. Be particularly careful in places
where the power supply is unstable. An incorrect power supply may result
in malfunction.
• Leave the label attached to the Unit when wiring. Removing the label may
result in malfunction.
• Remove the label after the completion of wiring to ensure proper heat dis-
sipation. Leaving the label attached may result in malfunction.
• Use crimp terminals for wiring. Do not connect bare stranded wires
directly to terminals. Connection of bare stranded wires may result in
burning.
• Do not apply voltages to the input terminals in excess of the rated input
voltage. Excess voltages may result in burning.
• Do not apply voltages or connect loads to the output terminals in excess
of the maximum switching capacity. Excess voltage or loads may result in
burning.
